How to get more storage
To increase your storage quota, you need to buy more Microsoft storage.
If you are a free user, you can buy a subscription.
If you are already a Microsoft 365 Personal & Family subscription holder, you can add up to 1 TB of additional file storage to the 1 TB already included with your Microsoft 365 subscription.
Consumer mailbox limits are capped at 50 GB. To get back under your storage quota, you need to free up storage space. If you need more than 50 GB mailbox, see our Enterprise plans.
